GEORGE W. scimmia, or NEW YORK',` n. Y.y

ririi-stiiiivii.

To all 'ui/wm t may concern.'

Be it known that I, GEORGE WV. `So'rionnn, a citizen of the United States, and resident of New York city, borough of-Queens, in the county of Queens and State ofNew York, have invented certain new and useful Improvementsin Pipe-Sleeves,of which the following is a specification.

The object of my invention is to provide simple and etlicient means to resist passage of gases, smoke and acid fumes, as well as the leakage of water from the surface 'of floors, around steam pipes, stand pipes, etc.,

passing through floors in buildings. Y

In carrying out my invention I embed orinsert inthe floors of buildings sleeves which encircle pipes passing through such floors, which sleeves rise above the surface ofthe ioor to a suitable heightyaiid I provide such? sleeves with lateral extensions or flashings embedded in the floors to prevent leakage or seepage of water through the floors along the sleeves to the ceilings below, the floors. Such sleeves are spaced froinfthe pipe or fitted loosely thereon in such manner as to permit freedom for eX' pansion and contraction of the pipe vwithin the sleeves. Packingmay be introduced between the sleeves and the pipes toprevent leakage between the sleeves aiidpipes in case of gases or smoke risingr from below orfwater on the floor rising vhigher than tlieltops' of the sleeves.

My invention further comprises novel details of improvement and combinations of parts that will be more fully hereinafter set forthand then pointed outin the claims.

`lwefei'encefis to be had tothe accompanying'drawings forming part hereof,fwherein,

Figure l is a vertical section illustrating my improvements installed in a floor; F ig. Ila is a detail hereinafter referred to, Fig. 2

iS a sectional view illustrating a modiiliea-` tion, Fig. 3 is avertical section illustrating a modification, andITig. 4f is a section on the line 4, 4,/in Fig. 3.A f

A pipe l, such as for carrying water, steam,waste or the like, may be installed in a building in any usual or suitable manner,\and as usual passes through the floors. At 2 isa sleeve orpipe section fitted in the floor and freely surrounding the adjacent portion of pipe l. The upper edge of sleeve 2 is tobe located at a suitable height labove the surface of the floor to prevent water upon the floor, 'up to such height, from y Specification of Letters Patenti i Appii'cationaied April 2i, 191e. f serial No. 92,632.`

flowing between thepipeland sleeve. The

sleeve 2, at they lower portion within? the' iioor, is provided withan extension 3f ein'- bedded in the floor; As illustrated in Fig". l, such` extensiony mayl be in the: `form .of

a wellknown flashing of suitable material.`

Such flashing may be of disk-like form havying an aperture receiving the'flowerp'ortion of `sleeve2, and said sleeve is shown pro;

vided with an annular exteriorflange 4 to` which the `extension or flashing 3 may be Secured in any suitable manner, suchI as'by bolts or screws vpassing throughthe flange,v

clamping a ring `6y against extension" or flashing 3. At 7 is a supplementallor eX- tension sleeve fittedwithin the" floor, enter# ing sleeve 2 and spaced Ifrom pipe `l.;'l`h'e sleeve 2 may be of asubstantial material,` suchas castiron, brassfor the like,'while supplemental sleevey 7 maybe of relatively" thin inferior material, suchas slifeetriron, galvanized, tinned' or thelikel. The supplemental sleeve 7 mayliave lany desired number of extensions` 8,: such' asf? angle pieces riveted or otherwise? securedto the' sleeve,"

one `or more projections at 10, tol temporarily rest upony the usual-*wooden bars' lor boarfls 11', that are installed-to receive' the floor arch 9 when the latter is laid. Taeks or the like, vindicated at 12, (Figs.V lL and la) may be driven through flange Vor pro'- jection l0 into the boardsI ll to'temporarily' retain supplemental sleeve 7 in position. Said tacks l2 kare shown having shoulders to rest against flange or projection y10, whereby the boards'll maybe readily re(` moved from below theV sleeve 7 by with? drawing the boardsV from the tacks:

In order to' providefrneansffor readily packing the space between pipe 1 and sleeve 2 at the upper portion ofthe latter, I have shown sleeve 2 provided withv an` interior rib or projection 13 upon which aring1l4,

preferably' a split ring,"fi`nay` be placed, which ring may fit loosely againstfthe inte-` rior of sleeve 2 and firmly against .theextee rior of pipe l when `forcedjinto place@` At 15 is a packing, such as mineral woolor the like, forced into the `space betweenpipe l and sleeve 2 upon ring 14C, to resist passage of gases, smoke, acid fumes "or waterbetween pipe 1 and sleeve2 from one'floor' to another.

Instead of providing sleeve 2 with an extension in the form of a flashing, as illustrated in Fig. l, said sleeve 2b may have an extension 3a cast integrally therewith of desired diameter, as indicated in Fig. 2, to resist the seepage or passage of water downwardly along the outer surface of such sleeve or supplemental sleeve 7b to the ceil- Y ing below. Instead of the supplemental sleeve terminating at itsV lower end within the floor arch, such sleeve may extend through the floor arch and through the plaster below the same, and the lower end of said sleeve Ymay be turned inwardly at. 7a toward pipe 1, as illustrated in Fig. 2, serving as a guide against pipe 1 when the parts are being installed. Any suitable finish may be applied to the extending end of sleeve 7b, such asceiling rosettes and the like.

My improvements may be installed in a floor as follows: If the pipe 1 is erected in a building priory to the installation of the floors, thesleeves 2 and 7 and ring ylli may be applied upon the lengths of pipe before the latter are coupled together. When the boards 11 are placed in position for receiving the floor arches, the sleeve 2 may be slid along the pipe above such boards, and the sleeve 7 then may berested upon such boards and the projections 10 tacked thereto to retain the sleeve in proper'position around the pipe l, the sleeve 2 then being held up above such boards in any suitable manner. The iioor arch may then be laid upon boards 11 and embed sleeve 7. When the concrete filling at 9a is to be installed, the sleeve 2 is lowered over the upper part of corresponding sleeve 7 to rest upon the respective floor arch 9, thejsleeve 7 retaining the sleeve 2 in position around pipe 1, and then the concrete filling 9 is installed and einbeds sleeve2 and its extensions or flashings leav- `ing a suitable portion of sleeve 2 projecting above such filling. Thereafter the packing 15 may be inserted between the pipe and sleevew2. When the boards 11 are removed, sleeve 7 will remain in position, since the sleeve, the extensions S and tacks 12 are einbedded in the floor arch, and then the ceiling plaster 16 and finish at 17 may be applied as usual to the floor arch.

Instead of sleeve 7 or 7b being supple- I mental to sleeve 2 or 2b the latter sleeve may be made sufficiently long in a single piece to extend through the ceiling, as shown at, 2C' in Fig. 3. In such case sleeve 2c may Y have projections at 10a to rest upon boards 11, the inturned lower end 2a of sleeve 2C serving as a guide against pipe l when the installation is being made.

The sleeve 2c has the extension 3b embedded in the material of the floor. The lower endof sleeve 2c below the ceiling may be suitably shaped and adapted to receive the ceiling rosette in manner described with respect to sleeve 7b of Fig. 2.

The filling 9CL may be extended up at 9", as illustrated in Fig. 3, in the form of a curb above the floor level around the portion of sleeve 2c that extends above the floor, to prevent leakage of water between the floor and the sleeve 2c which might occur at a joint between said sleeve and floor, the curb 9b being preferably carried to the top edge of sleeve 2c before the water rises to the top edge of the curb and sleeve.

While I have illustrated the curb 9b in Fig. 3, it will be understood that the same may be applied in connection with the arrangements illustrated in Figs. 1 and 2.

My improvements are simple and inexpensive to manufacture and install, and have the advantage of enabling the iiooring to be securely fitted to the sleeve when being installed, so as to resist seepage or leakage of water from the floor to the ceiling below, as well as to resist the passage of gases, acid fumes and smoke around the pipe from Hoor to iioor. Furthermore, since the portion of sleeve 2 projecting above the floor level extends for a suitable height, the water that'accumulates on the floor by reason of overflow from surface pipes, washing the floors, or from lires, is prevented from leaking along the pipes to the ceiling below, yet pipe 1 has freedom for contraction and expansion through the floor and within the sleeve without the tendencyrof causing looseness between the pipe and floor, which would permit seepage or fiow of water, gases etc. through the iioor along the pipe.

Having now described my invention what I claim is l. rI`he combination of a molded Hoor, a pipe fitted freely therein, and a sleeve embedded in the floor and extending above the same and freely surrounding the pipe, permitting expansion and contraction of the pipe within the sleeve, said sleeve having an extension extending laterally around the sleeve, said sleeve and extension embedded in the floor to prevent leakage of water through the iioor along the exterior of the sleeve.

2. The combination of a molded floor, a pipe fitted freely therein, a sleeve embedded in the floor and freely surrounding the pipe, permitting expansion and contraction of the pipe within the sleeve, and a supplemental sleeve embedded in the fioor and loosely receiving said pipe, said sleeves being fitted one to the other, one of said sleeves having a laterally disposed extension surrounding the sleeve embedded in the floor to prevent leakage of water through the floor along the exterior of the sleeve.

3. The combination of a floor, a pipe 'tted freely therein, a sleeve fitted in the floory and extending above the same, and freely surrounding the pipe, permitting expansion and ico contraction of the pipe within the sleeve, said sleeve having a flange, and a dashing secured to said flange, the flange and said flashing being embedded in the floor.

4. The combination of a molded Hoor, a pipe itted freely therein, and a sleeve embedded in the floor and extending above the same and freely surrounding the pipe, per mitting expansion and contraction of the pipe withinthe sleeve, and having an inturned end portion surrounding the pipe, said sleeve having an outward extension surrounding the sleeve and embedded in the Hoor between the upper and lower surfaces thereof to prevent leakage along the sleeve within the floor.

5. The combination of a molded floor, a

bedded in the floor and extending above the same and freely surrounding the pipe, permitting expansionl and contraction of the pipe within the sleeve, said sleeve having an outwardly disposed extension embedded in the floor, the floor having a raised curblike portion surrounding the upper portion of the sleeve above the floor level to prevent leakage of water from the floor level between the sleeve and the floor.
